Micro Autoclavable

 
Micro Autoclavable Electrodes  

This series of miniature steam, sterilizable, combination pH and redox electrodes are designed for small benchtop fermentors and culture apparatus. To conserve space, the electrode of constructed with a 6mm O.D. immersion shaft. When compared to the standard 12mm type, it is relatively small, making it desirable for shallow culture flasks and fermentors.

The immersion “A” length of the electrode can be ordred from 25mm to 300mm.

The electrode can withstand steam sterilization up to 130°C and features the pHoenix detachable cable assembly which is detached during autoclaving.

Electrodes are available with a double junction reservoir. The double junction reference reservoir is recommended, in most cases, for long term stability and life expectancy. A double electrolyte bridge eliminates poisoning caused by the presence of certain ions such as sulfide. Sulfide reacts with silver, forming silver sulfide deposits in the reference junction. The electrode is constructed with an annular ceramic reference junction, concentric with the pH bulb. This eliminates clogging problems that normally occur in most electrodes used in fermentation.

The electrodes are designed to fit all 12mm and 6mm electrode holders or rubber stoppers used in benchtop fermentors.

When ordering, specify immersion length “A”, the distance from the point of penetration inside the vessel to the tip of the probe.

A detachable electrode cable must be ordered separately.
